Accounting for language background differences in the Australian National Assessments – Literacy and Numeracy

This study examines language background differences in the Australian National Assessments – Literacy and Numeracy (NAPLAN), and the extent that language background differences are accounted for by socioeconomic background, schools and contemporary influences. There are sizable, sometimes very large, differences in performance by language background. Students with Eastern and Southern Asian language backgrounds exhibited high, sometimes very high, mean scores, whereas students with African, Central Asian and Pacific language backgrounds had relatively low mean scores. Language background differences tended to be larger for numeracy than for reading. Parental occupation and education accounted for some of the effects of language background for some groups, but not for Asian groups. Generally, language background effects cannot be attributed to the unequal distribution of language background groups across schools. When considering students' prior achievement, most language background effects, including all language backgrounds with strong negative effects, were reduced substantially often to statistical insignificance. The exceptions are Chinese and other East Asian and Southern Asian language backgrounds.     

Reduced forms and weak instrumentation

ABSTRACT

This paper develops exact finite sample and asymptotic distributions for a class of reduced form estimators and predictors, allowing for the presence of unidentified or weakly identified structural equations. Weak instrument asymptotic theory is developed directly from finite sample results, unifying earlier findings and showing the usefulness of structural information in making predictions from reduced form systems in applications. Asymptotic results are reported for predictions from models with many weak instruments. Of particular interest is the finding that, in unidentified and weakly identified structural models, partially restricted reduced form predictors have considerably smaller forecast mean square errors than unrestricted reduced forms. These results are related to the use of shrinkage methods in system-wide reduced form estimation.     

Toward a More Expansive Understanding of Family Communication: Considerations for Inclusion of Ethnic-Racial and Global Diversity

Building off essays by Gudykunst and Lee (2001) and Turner and West (2003), the purpose of this essay is to emphasize the need to be more inclusive in family communication research in terms of ethnic-racial and global diversity. After discussing the current state of scholarship, we outline important considerations for the field of family communication to achieve this goal.     

Research ethics review for the use of anonymized samples and data: A systematic review of normative documents

While the anonymization of biological samples and data may help protect participant privacy, there is still debate over whether this alone is a sufficient safeguard to ensure the ethical conduct of research. The purpose of this systematic review is to examine whether the review of an ethics committee is necessary in the context of anonymized research, and what the considerations in said ethics review would be. The review of normative documents issued by both national and international level organizations reveals a growing concern over the ability of anonymization procedures to prevent against reidentification. This is particularly true in the context of genomic research where genetic material’s uniquely identifying nature along with advances in technology have complicated previous standards of identifiability. Even where individual identities may not be identifiable, there is the risk of group harm that may not be protected by anonymization alone. We conclude that the majority of normative documents support that the review of an ethics committee is necessary to address the concerns associated with the use of anonymized samples and data for research.     

GMM Estimation of Autoregressive Roots Near Unity with Panel Data

This paper investigates a generalized method of moments (GMM) approach to the estimation of autoregressive roots near unity with panel data and incidental deterministic trends. Such models arise in empirical econometric studies of firm size and in dynamic panel data modeling with weak instruments. The two moment conditions in the GMM approach are obtained by constructing bias corrections to the score functions under OLS and GLS detrending, respectively. It is shown that the moment condition under GLS detrending corresponds to taking the projected score on the Bhattacharya basis, linking the approach to recent work on projected score methods for models with infinite numbers of nuisance parameters (Waterman and Lindsay (1998)). Assuming that the localizing parameter takes a nonpositive value, we establish consistency of the GMM estimator and find its limiting distribution. A notable new finding is that the GMM estimator has convergence rate , slower than , when the true localizing parameter is zero (i.e., when there is a panel unit root) and the deterministic trends in the panel are linear. These results, which rely on boundary point asymptotics, point to the continued difficulty of distinguishing unit roots from local alternatives, even when there is an infinity of additional data.     

Nonlinear Regressions with Integrated Time Series

An asymptotic theory is developed for nonlinear regression with integrated processes. The models allow for nonlinear effects from unit root time series and therefore deal with the case of parametric nonlinear cointegration. The theory covers integrable and asymptotically homogeneous functions. Sufficient conditions for weak consistency are given and a limit distribution theory is provided. The rates of convergence depend on the properties of the nonlinear regression function, and are shown to be as slow as n^1/4 for integrable functions, and to be generally polynomial in n^1/2 for homogeneous functions. For regressions with integrable functions, the limiting distribution theory is mixed normal with mixing variates that depend on the sojourn time of the limiting Brownian motion of the integrated process.     

People who live apart together (LATs) – how different are they?

‘Living apart together’– that is being in an intimate relationship with a partner who lives somewhere else – is increasingly recognised and accepted as a specific way of being in a couple. On the face of it, this is a far cry from the ‘traditional’ version of couple relationships, where co‐residence in marriage was placed at the centre and where living apart from one's partner would be regarded as abnormal, and understandable only as a reaction to severe external constraints. Some commentators regard living apart together as a historically new family form where LATs can pursue a ‘both/and’ solution to partnership – they can experience both the intimacy of being in a couple, and at the same time continue with pre‐existing commitments. LATs may even de‐prioritize couple relationships and place more importance on friendship. Alternatively, others see LAT as just a ‘stage’ on the way to cohabitation and marriage, where LATs are not radical pioneers moving beyond the family, but are cautious and conservative, and simply show a lack of commitment. Behind these rival interpretations lies the increasingly tarnished spectre of individualisation theory. Is LAT some sort of index for a developing individualisation in practice? In this paper we take this debate further by using information from the 2006 British Social Attitudes Survey. We find that LATs have quite diverse origins and motivations, and while as a category LATs are often among the more liberal in family matters, as a whole they do not show any marked ‘pioneer’ attitudinal position in the sense of leading a radical new way, especially if age is taken into account.     

Developing a Program in Sociological Practice: Program Structure,Curriculum Design,and Professional Culture

A sociological practice program has much to offer an undergraduate sociology department that wishes to make itself more relevant to its students, university, and larger community. Reasons are explored for why a department might choose to transform its program from a more traditional liberals arts focus to that of sociological practice. A discussion of the programmatic content of a practice program, including structure, curriculum design, and professional culture, is detailed. The experience of Our Lady of the Lake University in developing its accredited undergraduate sociological practice program is offered as an example of program development.     

Latent Models of Family Processes in African American Families: Relationships to Child Competence,Achievement, and Problem Behavior

This study explored the assessment of family processes for a sample of African American kindergarten children, parents, and teachers involved in the EARLY ALLIANCE prevention trial. Using modified versions of the Family Assessment Measure, the Family Adaptability and Cohesion Evaluation Scales, the Family Beliefs Inventory, and the Deviant Beliefs measure, internal consistency analyses along with exploratory and confirmatory factor analyses provided empirical support for a Cohesion factor (cohesion and communication), a Structure factor (support and organization), a Beliefs factor (on family purpose and child development), and a Deviant Beliefs factor. Regression analyses examined the relationship of these measures of family processes to child social and academic competence, problem behavior, and early reading achievement. Family Structure (support and organization) was consistently related to parent‐ and teacher‐reported competence and behavioral outcomes, providing support for this construct as an important aspect of family process. Family Cohesion and communication, along with Beliefs, were also related to youth competence and behavior. None of the family process variables added a unique contribution to the influence upon achievement for these kindergarten children beyond the role of parental education and income. This work begins to examine specific dimensions of family processes and their relationships to important adaptive and less adaptive child outcomes. Other dimensions may be identified and examined in future research with families of color.
